Top Mistakes in Choosing and Using Linear Guides


Linear guides are accuracy mechanical assemblies that function as part of a system. As such, they could only act to the degree that they are correctly incorporated into the overall machine. Simply specifying the suitable guide is not sufficient. Building a system that functions as intended needs a clear perspective of how to specify, install, design, plus test the linear guide or telescoopgeleider. Here, we discuss numerous of the most common mistakes made by designers making linear guides into their system, and methods to avoid them.

Not fabricate mounting surfaces toward tolerance.

Linear guides are accuracy-ground at the factory to function with least friction. In a perfect world, the friction of each entity linear guide block will be the same whether it is mounted otherwise not mounted. In realism, any misalignment otherwise out of smoothness of the mounting surfaces straight adds pre-load into the linear guide system.

Not counting mounting features for alignment.

 Precision linear guides need appropriate alignment to guarantee performance to specification. Mainly in a volume built-up scenario, additional mounting features could speed the installation procedure and guarantee effective performance. These could be as simple as a pair of alignment pins that aid align the main rail, together with an assembly process for align the secondary rail.

Not specifying preload correctly. 

Preload in a linear guide or telescoopgeleiderinvolve selecting the diameter of the balls in micron increment to adjust the fit among the block plus the rail. In accuracy applications, it is usually beneficial to have several positive preload, which means that there is no clearance among the block, the rail, as well as the ball. Depending on the application, the balls might even experience some compression. Correctly specified, preload could reduce negative factor for example noise, heat generation, vibration, and deflection. Improperly specific, though, preload can extensively increase friction as well as degrade system performance.
